Wire color code standard

Hewwo, all.· I haven't been into robotics as a part of the big picture for long.· I was just wondering does the field of "hobbyist" robotics have a wire color code standard?· I have been told to look at various bot setups and such and tried to find out from the pics just how the wires were routed and used.· I got confused.· Is there some kind of standard or do different biulders just use whatever colors they got?·

For a beginner, it is really easy to over-buy wire.
If you are really trying to figure out your choices,
buy a one meter (or one yard) hunk of solid 22 guage, 25 wire cable, remove the outer covering, and you will have an ample sellection of colors -- including stripes.
The solid 22 guage is commonly used on the breadboards. If you get strand wire by mistake, it is still useful for flexible connections between circuit boards and outboard devices.
DO NOT buy spools of wire in a variety of colors. You will never finish using them (unless you need to install a lot of doorbells and intercoms).

Red and Black. While most electronic project use these colors aas RED(+) and Black(-) you will find very few of these colors on 24v industrial photo eyes like a Banner or AB right sight. Mostly where I find RED and Black is for 5v dc use only. Red is normally a designator for a switched 110v ac and Black a non switched 110v ac supply. Where as white is for the Nuetrall of the 110v ac supply. White is also used as the sink on most 24v photo eyes and proxie switches also.
Green or Yellow/Green is ALWAYS used for a ground. No exception.
Brown, Yellow, and Orange are used for 480v ac.
Grey or Nuetral is used for the Nuetral of a 277v ac line.
Blue is for +/- 24v dc in cabnets
Blue is also for -24 v dc for photo and proxie switches.
Brown is for +24v dc for photo and proxie switches.
Black is for the source for photo and proxie switches
white is for the sink for photo and proxie switches.
It is common also to see yellow used for power of 110v ac for machines that need power when the main machine shutoff is off but the ceiling shutoff is still on.
In electronics though usually you would use ide or ribbon cableing for wire. The type of wire that is all glued together or housed together in a cable.
If you really get down to it. Usually there is no color code for electronics per say other than this since most electronics do not use wire but use boards. Then they follow the electrical color coding since you are connecting industrial switches and wiring to them.
Just my 2 cents.
So that people aren't confused, I still think the Red & Black for Vcc & Vss should be standardized, and then what people use for their signals should really be their preference unless their project will interface to a design with a known color code for the wiring.
Phones are Cars are totally different too...

I would also·recommend buying a short·length of multicore cable to get a variety of colors if you want them.
A typical 25 pair cable will have Blue Orange Green Brown Grey as primary colors, and White Red Black Yellow Violet as the secondary, giving the 25 combinations of twisted pairs. There are lots of other variations though from different manufacturers.

I don't mean to be peculiar, and pedantic, but if you want to see some strange colors, then I suggest you should examine the 50 colored wires that make up the AMP connector wire, that's the RJ21X stuff. The interstation wire, that can be bought from GreyBar that's two conductor is typically just one specific pair.
There are fifty seperate wires, that reproduce their functions across all of them.
